Subject: trace-cmd: new package
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=07203d78c24d;p=buildroot.git

trace-cmd: new package

This commit adds a new package for the trace-cmd tool.  This tool is a
command line front end of ftrace.  It collects traces on your target.
You can analyse these traces on the target or on the host via the gui
"kernel shark".

[Thomas: use TARGET_CONFIGURE_OPTS, define _GNU_SOURCE to get
O_CLOEXEC definition on uClibc, add thread and largefile
dependencies.]
